Massey Ferguson - Track Tensioning

New_Digger · Feb 17, 2015

Hello all, new to the site. I've searched but I can not find the answer to my question (and a link to a manual for purchase is not an answer IMHO).

1. Is the MF400 track adjustable via grease gun (hydrolic pressure) or is there some other way this guy needs to be tensioned? If so, where is the fitting to accomplish this? I can't seem to figure it out... I've tried!

2. Is the usual 1 - 1 1/2 inches of sag acceptable for each track to be considered adjusted?

Thank you!

Not familiar with this tractor, however there may be a specification for it in regards to correct track tension. Ones I am familiar with tend to allow for 1-1/2" to 2" of free play above the top roller, when prying up with a bar.

A picture might help.

If your idlers have a hydraulic (grease
pumped)/tensioner, sometimes the zerk is in a recess on
top of the yoke and the recess gets filled with mud
or dirt. Some poking around with a screw driver
blade might help find the zerk

Thank you. Yes is was quite filthy (still isn't "Clean") when I got it. Here's a pic of the track - maybe it'll pop out.

I think you will find that the hex just to the left of the spring is the adjustment. We used to call 1 to 1.5 inches sag on the track good. Usually a little toward tight on hard surfaces and a little looser in softer conditions, if I recall correctly, been awhile.
